Field Description
Channel Parameters
Noise Level
The level of the system noise power in dBm. Nominal noise level
without interference is -97 dBm. Higher values indicate higher
noise levels due to interference presence.
Note: Noise level will show N/A after reboot. It will update after
4~6 minutes up time when the Calibration cycle 0 is done.
Beacon Success Ratio
The ratio, in percentage, between the number of beacons that
the BST transmitted and the beacons that the BST should have
transmitted. A low percentage indicates lost beacons probably
due to high activity in the channel (CCA is high) that does not
enable transmission.
Idle Time
The relative amount of time (in percentage from the 100% of the
total time) that the system is neither transmitting nor receiving.
Maximum performance from the unit is achieved when this
number is low. Together with the “Interferences” and “Others”
counters helps to detect high-interfered links. It is affected from
the environment activity of other wireless devices and from its
own activity.
Tx Activity
The relative amount of time (in percentage from the 100% of
the total time) in which Channel was busy transmitting data.
Rx Activity
The relative amount of time (in Percentage from the 100% of the
total time) in which Channel was busy receiving valid data that
was successfully decoded and was aimed to the WBS.
Other WiFi activity
The relative amount of time (in Percentage from the 100% of the
total time) in which Channel was busy receiving valid data not
aimed at the specific WBS (data from other networks).
Interferences
The sum of Invalid CS Packets (reception that failed to be
modulated correctly) and Invalid ED Packets (energy was
detected but no valid carrier was found) activities (in Percentage
from the 100% of the total time).
SDMA Parameters
SDMA activity
The percentage of packets that were transmitted using SDMA
from the total amount of packets transmitted.
